Highly recommend! Garry, well done!! To anyone reading this review: This company is so outstanding that my significant other and I are actually going to miss seeing the crew show up to work on our roof. (Not kidding.) The roof is absolutely beautiful and the wood repair impressive. Roofing is hard work, yet the crew had the most amazing, friendly and helpful attitude you can imagine. Garry, Bob, Jose and Claudio, and all of the crew for that matter, made certain every detail was addressed. Each deserves singular praise as incredibly honest, professional and just plain fantastic individuals to work with. I wish I could remember the names of all of the crew as they were all terrific. A sincere thank you to Preferred Roofing! BRUCE2020-03-09Trustindex verifies that the original source of the review is Google. Great guys, and an even better price than anyone else. Good quality work.
